How do you know whether you should add or subtract when using the elimination method?
When using the elimination method to solve a system of equations, you should add the equations if doing so will eliminate one variable. This typically occurs when the coefficients of that variable are opposites (e.g., +2 and -2). Conversely, you should subtract the equations if their coefficients are the same, which will also help to eliminate that variable. Ultimately, the goal is to manipulate the equations to create a situation where one variable cancels out.
What can you do with abacus?
You can use an abacus to add and subtract quantities of beads by moving the them around. This can in turn help to solve equations involving counting numbers.
